Suing a non-paying client is the most expensive way to collect a debt. This guide walks through the five-step collections sequence I use in Florida to recover an unpaid invoice before litigation — quiet and precise early, decisive and well-supported late.
For the strategy behind the sequence, see the companion article on the five-step collections sequence before you sue. For the anatomy of the letter that does the heavy lifting, see the seven elements of a Florida demand letter that gets paid.
Inputs you need before starting
- • The signed contract, change orders, invoices, and proof of delivery or acceptance.
- • A running balance: principal, credits, and the exact amount owed as of today.
- • The Sunbiz record for the paying entity, registered agent, and any guarantors.
- • The contractual notice party and the applicable statutory framework (§687.01 interest, contract fee clause, §57.105).
- • The court of competent jurisdiction and the cause of action you would actually file.
Mistakes to avoid
- • Filing suit first, before confirming the debt and documenting the account.
- • Demanding payment from the wrong entity because the check came from a different name.
- • Sending angry emails that become evidence against you instead of a factual record.
- • Setting a vague deadline instead of a specific calendar date.
- • Escalating an invoice that is not worth the cost of the fight.
Step 1: Confirm the debt and the right legal entity
Build the running balance from the contract, invoices, and written acceptance, then confirm who actually owes it. Pull the Sunbiz record and match the exact legal name, registered agent, and any personal guarantor named in the contract. Businesses hide behind the wrong entity constantly — a demand aimed at the wrong party is one the debtor can ignore for free.
Step 2: Send a documented account statement
Before the lawyers, send one clean, unemotional statement of account: each invoice, date, amount, running total, and a short, specific deadline to pay or call. It gives an honest counterparty a frictionless way to fix an oversight and builds the paper trail that strengthens every later step. Replace the angry-email chain with a record that reads well in front of a judge.
Step 3: Send an attorney demand letter
This is the step that does the heavy lifting. The letter identifies the correct party, states a tight factual chronology, cites the contract provision in default and the applicable Florida statute, states a sum certain including statutory interest under Florida Statutes section 687.01, sets a hard calendar deadline, and names the specific consequence — the court, the cause of action, and the basis for a fee claim. On firm letterhead, sent certified mail with delivery documented, it tells the recipient exactly what happens next.
Step 4: Evaluate the response — settle, structure, or sue
A good demand letter usually produces a response within days: full payment, a settlement offer, or a request for a payment plan. Make a business decision, not an emotional one. A straightforward breach-of-contract case in Florida can cost $15,000 to $50,000 and take a year, so a structured payment — documented with an acceleration or confession-of-judgment clause — often beats the fully litigated win.
Step 5: File suit — as a last resort
If the deadline passes and the debtor stays silent, you file from strength: a documented debt, a confirmed party, an account statement, and a demand letter that laid out exactly this outcome. That record supports the complaint, the interest claim, and any fee claim. Suit is not a failure of the sequence — it is the sequence working as designed.
